Although so named because John Cator the younger established the park between 1757/60 and 1785 and acquired the rights of the Manor of Beckenham, it transpires that most of the land in the current park was in the neighbouring Manor of Foxgrove and some nearby Lewisham Lands that once belonged to the Forsters of Southend, Lewisham and the Earl of Rockingham/Sondes/Lees Court estate. Several accounts of the history of the park require amendment due to recent rediscoveries from different archives. The Friends of Beckenham Place Park endeavour to compile an accurate history based on archive material in the British Library, Kent, Essex and Surrey Archives.

Beckenham Manor has medieval origins and is mentioned in the Domesday Book as belonging to the Bishop of Bayeux. In the 17th century, the whole estate was owned by Walter St John, and later by Frederick Viscount Bolingbroke, who sold the estate with manorial rights passing to the noted Quaker and MP John Cator in 1773. Records show John Cator acquired land here as early as 1757 and built his house by 1762. Cator built the mansion that stands today.
Cator's father-in-law, botanist Peter Collinson, visited in September 1762, commenting:
"... went, for the first time, to visit my son-in-law John Cater [sic] (who married my daughter), at his new-built house, now finished, at Stump's Hill, half-way (on the south side of the road) between Southend and Beckenham, in Kent, began in the spring 1760, on a pretty wooded estate that he had purchased. The plantations about it, all of his own doing, I found in a thriving condition, and when grown up will adorn so stately a house, in so delectable a situation, and make it a Paradise."
Cator, reputed to be friends with Swedish botanist Carl Linnaeus, introduced many exotic tree species and a lake, which is now dry. Even today, there are reputed to be 60 species of tree on the estate. The association is unlikely but Cator's father in law had met Linnaeus in 1735/36 and continued a lifelong correspondence with him exchanging plant specimens and philosophical discussions. Collinson writes about Cator and his own son that they both pester him for plants from his own garden at Mill Hill and requests Rhodedendrons, Kalmias and Azaleas from his friend John Barham in America.
The mansion remained with the Cator family until the 20th century, although inhabited by tenants for most of the 19th century - including a boys school and sanitorium in the early 20th century - before being bought by London County Council in 1927. In 1929 the golf course (established in 1907) became the first municipally owned course in England (and also reputedly the busiest), while the mansion was retained as a clubhouse. During the Second World War, the park became a prisoner of war camp and defensive measures including anti-aircraft battery and barrage balloons were installed.
The park was managed by the Greater London Council from 1965, then by Lewisham borough council from 1972. In 1995 after boundary changes the park is entirely within the Borough of Lewisham - formerly falling within two boroughs according to boundary markers which can still be seen in Summerhouse Hill Wood.
